HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 316,827, dated April 28, 1885.

Application filed January 20, 1885. (No model.)

To all whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new anduseful Improvement in Heel-Attaching Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in which- I Figure 1 is a vertical central section of a machine containing the features of my inven- Fig. 2 is a plan view thereof. Fig. 3 is a View in vertical section of a portion of the templet or pressure plate and yielding templet-block anda heel-blank. Fig. represents a section showing the same parts, and also the awls and awl-holder, the yielding templetblock having been moved down and latched to clamp the heel-blank upon the heel-support. Fig. 5 represents in vertical section the same parts shown in Fig. 3, with the drivers and driver-block in position, showing the manner of releasing the devices which hold or look down the yielding templet-blocks. Fig. 6 is a view,part in front elevation and part in vertical section, of my machine. Fig. 7 represents in vertical section a templet-block and a top-lift-holding device or plate.

The invention is an improvement upon that described in my application for Letters Patent of the United States, filed January 20, 1885, Serial No. 153,388. It embraces a construction whereby three or more jacks or heel-supports are fed in. succession to the pricking, driving, and spanking devices, whereby the pricking of one heel, the attaching of another, and the spankingof still another are simultaneously performed. It still further relates to various details of construction, all of which will hereinafter be fully described.

A represents the central post or column, which is attached or bolted to the bed a. Upon this column is arranged, so as to slide thereon, the head B, which is shaped in plan substantially as shown in Fig. '2, and it supports a group of awls, b, a group of drivers, 6, and the spanker-block b", all in operative positionthat is, so placed upon the head that upon its reciprocation they are in a position to operate simultaneously. The head is reciprocated by the rod b link 12*, and crank b on the shaft 1), upon which is the driven pulley, or which is revolved by the pulleyshaft through connecting-gears.

The templet or pressure plate 0 is adapted to have a vertical movement, and also a revolving movement. It is moved vertically by means of the presser-block 0, which is attached to the cross-head B in the manner specified in my said application; but it does not continue entirely around the column, there being space left for the attachment to the column of a lever, hereinafter referred to. The templet supports a series of yielding templetblocks, 0, one for each jack or work-support.

These templet-blocks have a yielding movement in the templet-plate, in order that they may be used to clamp the heel-blank upon the boot or shoe sole, and hold it clamped while it is being pricked and while it is being transferred from the pricking to the driving devices, and while the attaching-nails are being driven. Each block 0 is arranged to fit into a hole made in the templet-plate, and they are supported therein by the springs c, which surround the guide-posts c", and they are held locked down by the automatic latches c, which are pivoted at each side of the block 0 to the templet or pressure plate in a recess out therein. and are by the springs 0 upon the down ward movement of the templet-block, moved upon the edge thereof to hold the same down. The latches 0 also prevent the springs c from forcing the templet-blocks upward too far by engaging automatically with the notches a cut in the side thereof, as shown in Figs. 8, 4, and 5.

D are the jacks, and they are arranged to slide upon the revolving table E, as described in my said application. The table is adapted to be revolved on the column,and ithas a sleeve, e, which connects with a sleeve, 0 extending down from the templet or pressure plate. The templet or pressure plate of course has a vertical movement in relation to the sleeve e,and it is lifted by the cross-piece c on the reciprocating rod Z)", as described in my said applica tion. The templet or pressure plates are automatically locked in position by a spring-bolt or other device, as described in my said application, and the'jacks may be automatically moved into and out of operation by the device described in my said application, or by the device described in an application of even date herewith.

In operation the boy or attendant places the boot or shoe upon the work-support; and, if he also locates the heel-blank, puts it in proper position, and he, by means of the lever F, which is pivoted to the column at f, and which has a pressure or bearing block, f", which is, by the movement of the lever, moved or pressed downward to move the templet-block 0 upon the heel-blank, clamps it firmly to the boot or shoe. The table is then revolved, bringing another jack before him, and the operation of placing the boot or shoe upon the jack or heel-support and clamping the heel thereon is continued. 'Meanwhile' the first jack with the heel clamped thereon has been advanced to a position under the awls, and the machine then makes a reciprocation and the heels are pricked or formed in the heel-blank. Upon the next movement of the revolving table E, the first heel-blank thus pricked is advanced to a position beneath the driving devices, and another or second heel is brought into position beneath the awls, a second reciprocation of the machine forms the holes in the second heel and drives the nails, which have previously been fed into the templet-block, into the first heel, and attaches it to the sole or soles of the boot or shoe, and another movement of the revolv ing table brings the first heel, which is now attached, under the heel-spanker, the second heel,which has been pricked, under the nailing devices, and a third heel under the awls. If the heel is to be blind-nailed, the top lift is then fed into position beneath the templetblock by the movement of the top-lift plate, so that the top lift is properly located, and a third reciprocation of the machine causes the heels to be formed or pricked in one heelblank, the nails to be driven through another heel-blank, and a top lift to be spanked upon another heel-blank, and the operation thus continues in this manner, each reciprocation of the head applying a top lift to one heel, driving the attaching-nails of another, and forming the holes in another. Upon the downward movement of the drivers, the latches c on the templet-block are moved back automatically by contact of the edge or lower corner of the block with the inclined surfaces of the latches, (see Fig. 5,) so that upon the upward movement of the drivers and driverblock the templet-block follows immediately thereafter, and also the templet plate, and the templet-block lifts with the driver-block, so that the latches cannot engage with its upper surface. This enables the top-lift plate to be moved with the top lift into position and renders the hand-unlatching of the templet-block unnecessary. Each yielding templet-block c is provided with a top-lift plate, G, which slides in a dovetail recess formed therein. One portion of this plate forms a templet and another portion carries the clamps or jaws for holding the top lift.

The portion which forms the templet should project below the portion carrying the t0p-lift holder, and it may be at one end or the other of the plate, as desired. It is preferable, however, that the top-lift holder be at the inner end of the plate, in order that the plates may be pushed away in while the templet or pressure plate 0 is being revolved, until it becomes unnecessary to locate or bring into position the top lift over the heel-blank. It will be observed that by this construction the operations of pricking, driving attaching-nails, and spanking are carried on simultaneously in different holes, that the heel and work can be transferred accurately from the pricking devices to the driving devices, and that the top lift can be easily applied.

For feeding the templets with nails I may use a nail-carrier, such as is described in a pending application, or I may use a separate or detachable nail-holder adapted to be filled and to be moved over the holes in the templet and to then deposit the nails therein.

It may not always be desirable for the at tendant to locate the heel-blank, and when he does not it is done by the operator, who places it in position upon the sole of the boot or shoe after it has been moved into position beneath the awls, and in that case the downward move ment of the awl-block automatically locks the templet-block down upon the heel-blank, so that the heel remains clamped in position until it is released automatically by the driverblock, as herein specified. The lever F is held up by means of the spring f. Of course I may use, in connection with each jack or heel-support,any of the shoe-centering devices or heel centering and holding appliances described in the various Henderson and also in my patents and applications.

In Fig. 7 the top lift holder plate and spanker-plate G is represented as locked in place, so that the holes in the part which forms a portion of the templet register with the holes in the remainder of the templet. The locking device comprises a spring-operated bolt or latch, g, which automatically enters either the templet registering-hole g or the top-lift and spanker registering-hole 9 Of course, this sliding templet, top-lift, and spanker plate may be used in connection with any templet-block through which nails are driven or from which expelled, and whether in the position shown in the drawingsthat is, beneath the templet-or inverted and on top of it.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1.
